Tramp Oil
Tramp oil is contamination by a lubricating oil, usually either slide-way or hydraulic oils, often with the presence of bacterial BioFilm.
- Key problems are related to the ability of the coolant to reject emulsification of tramp oils.
- Good demulsification can result in the perception of increased tramp oil.
- High tramp oil emulsification results in less visible tramp oil, but ultimately results in problems with skin irritation, sticky deposits, smoke and fuming, coolant filtration problems, poor sump life, and surface finish issues.
- Tramp oils often contain BioFilm. BioFilm is a protein carbohydrate complex that bacteria produce to protect themselves from external elements and take the form of a slime or mucus.
- Where high levels of bacteria are present the coolant emulsion can split, this sometimes gives the impression of heavy tramp oil when in reality it is the coolant concentrate
